摘　　要：白乃庙铜矿为钼、金、硫等元素的大型铜矿床,属华北板块北缘金属成矿带,海相火山沉积(变质)热液叠加(富集)复成因矿床,深部花岗闪长斑岩体及其外围具有巨大的找矿潜力。本研究范围处于白乃庙铜矿外围,根据区域成矿地质条件和化探异常显示找矿方向为萤石铜多金属矿,通过物化探工作的面积性测量,分析土壤测量、磁法测量和激电中梯测量的实测资料,对各异常的成矿潜力进行了综合评价,圈定找矿靶区,为后期的下一步的找矿工作指明了方向。The Bainaimiao copper deposit is a large copper mine with molybdenum, gold, sulfur and other elements, belonging to marine volcanic deposititon (metamorphic)- hydrothermal superposition (enrichment) complex genetic deposit at the metallic metallogenic belt in the northern margin of North China Plate. In this deposit, the deep granodiorite porphyry and its periphery have great prospecting potential. This paper is focused on the periphery of the Bainaimiao copper deposit. According to the regional metallogenic geological conditions and geochemical anomalies, the prospecting direction of this area is to find the fluorite copper polymetallic deposits. Through the area measurement of physical and chemical exploration, the data of soil survey, magnetic measurement and induced electric medium gradient method has been analyzed, and then the metallogenic potential of each anomaly has been compreshensively evaluated. The results point out the direction for the next step of the prospecting work.
